Advances In Intensity Modulated Neutron Therapy (IMNT): Improvement In Plan Quality and Reduction In Treatment Time through Beam Angle Optimization (BAO) and Field Co-Optimization

High linear energy transfer (LET) IMNT faces practical delivery constraints: low output rates (~55 MU/min), manual gantry and couch rotations (~3-5 min/field), and mandatory wait times (~1-2 min/field) for neutron activation concerns. Our standard-of-care (SO...

Dosimetric Impact of Proton Variable Relative Biological Effectiveness (vRBE) In the Treatment of Ocular Cancers

Proton radiation therapy (PRT) is an effective modality for ocular cancers. Substantial evidence indicates that proton relative biological effectiveness (RBE) increases with linear energy transfer (LET). In vitro DNA double-strand break (DSB) and cell surviva...
